HODGMAN, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO THE NATIONAL WATER MAIN CLEANING-COMPANY, A CORPORATION OF MAINE.

DEVICE FOR PASSING CABLES THROUGH PIPE-LINES.

Application To all inhomit may concern:

Be it known that I, BURT B. HODGMAN, a citizen of the United States, and a resident of East-Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Devices for Passing Cables Through Pipe-Lines, of which the following is a specification.

5 My invention relates to devicesfor passing cables through pipe lines, and is adapted -to prevent the stoppage of such a device in 'its passage through a pipe by a cup or a ortion of the cup being destroyed so as to ermit the water to -pass by the cup without carrying italong.

In practice, where a cup carrier having one compartment is used, it sometimes occurs that an obstruction in the pipe tears the cup, and it practically becomes useless, as the water or fluid will pass the cup with- 'outpropelling .it'through the pipe. I have found that by arranging the cup into a plurality of compartment-s, this is overcome, and my improved carrier described in the following specification and annexed drawings, is addressed to this feature.

n the drawings, Figurel shows my preferred form of carrier located within a section of pipe; Fig. 2 shows a cross section of 30. the same looking in the direction of the ar- Y rows in Fig. 1.

In the drawings, 1 is a shaft having an eyelet 5 to which the cable 6 is to be attached. I'f*-my--,carrier is to be provided with four cups or compartments, as shown in' the drawings, although, of course, it may be made of any number of compartments as desired, I construct the shaft 1 in the form of a split shaft, as shown in tl1e drawing, Fig. 2, having the four sections 1, 1", 1 and 1. On the end of the shaft I provide a nut 4 adapted to hold the ends of the split shaft together after the cups have been insorted in place. The four cups 2 shown in the drawings are made of any suitable material, although I prefer to use a flexible ma- Foreach of the comholding the terial such as leather. partments I provide means for pipe lines, a piston com Patented Aug. 20, 1912.

compartment in its desired form, such as the fiat springs 7 shown in the drawings. The edges of the material of which the cups are made, are placed between the sections of the split shaft, as shown in Fig. 2, after which the head or nut 4: is placed uponithe split shaft, thus holding the cups in posi 'ion holding the ends of'the split shaft in position. I sometimes attach the cups together by any suitable means such as a cord or strap 3 passing through openings in the cups and knotted on By means of my ily seen that if any part of comes destroyed by catching uponan obstruction within the pipe line, it will only affect that particular part. of the carrier which was destroyed, and will not affect the usefulness of the other compartments or cups. This also affords a great economy in saving of material.

Any number of cups may be used, depending upon the wishes of the user, although I prefer four, as shown. The number of on s to be used also depends somewhat upon tiie size of the pipe through which it is desired to have the carrier pass. The smaller the pipe, the fewer number of cups.

Having thus described my invention, what I claim as new, and desire 'to secure by Letters Patent, is:

1. In a device pipe lines, the combination of a shaft, a plurality of cups mounted on said shaft, and means independent of said shaft for connectin"! said cups together.

2. In a device for passing cables through the inner side ofthe same.

invention, it will be readfor passing cables through the carrier bepipelines, a plurality of cup-shaped propelling elements so arranged that said cups taken together substantially fill the opening in a given cross-section of the pi e line.

3. In a device for passin cab es through ose of a split shaft, a plurality of indepen ently acting )ropelling cups mounted on said 5 aft and held in operative relation to each other by said shaft, and a cap for holding the ends of said shaft together.

4. 111 a device for passing cables through I In testimony whereof, I have signed my -pipe' lines, a piston composed of a split name tq this'specification, in the presence of shaft, 8. plul ality of independently-acting twois ib'scribing witnesses.-
